摘要：

山东龙口姚家金矿床位于龙(口)—莱(州)断裂的黄县弧形断裂段, 根据区域地质背景和矿床地质特征分析了该矿床的成矿地质条件, 认为胶东群老变质岩是本矿床的初始矿源层, 初步分析了断层泥在金的沉淀富集中所起的作用, 弧形断裂主要的导矿和容矿构造, 弧顶为矿液的集中提供了最理想的场所,并认为弧形断裂的走向转弯处是下一步外围找矿的重点, 指出了找矿前景和找矿方向。

关键词: 成矿地质条件, 找矿方向, 黄县弧形断裂, 姚家金矿床, 山东

Abstract:

Located at Huangx ian arc-fault part of Longkou-Laizhou fault belt. According to regional geological background and geological charactisitic of this gold deposit, The autho ranalyzes its ore-forming conditions, considers that old metamor phic rocks(Jiaodong group) are preliminary source rocks and simply illustrates fault gouges role dur ing gold-ore deposition and enrichment. Arc-fault is the main tectonic of inducting and depositing of gold ore. The top of arc is the finest place of centralization of fliud which includes gold-ore. The author considers that swerve part of fault is emphases of ore-prospecting in outplace of this gold deposit and points out ore-prospecting or ientation.

Key words: Minerogenetic geological condition, Ore-prospecting orientation, Huangxian arc fault, Yao jia gold deposit, Shandong province
